A couple of days ago I bought an Acer Aspire V3-571G laptop without a system installed on it. The only thing that was there was Linux Linpus. I created a bootable CD with Ubuntu 12.04 64-bit - I read that my processor was 64 bit and that it might be a good configuration for my gear (I'm not especially fluent with all the computer stuff, still trying to learn) and replaced Linpus with Ubuntu.

Everything seemed to work fine, but there're few exceptions to that which came pass my way.

My bluetooth doesn't work. It seems to be switched on, but when I check my system settings the button is actually off, and I can't drag it 'perminently' to the 'on' position. Tried a couple of commands I found on the net, none of them helped and there was no word whatsoever in my BIOS settings about enabling bluetooth.

My card reader has some serious problems with copying more than one file at a time. I tried to put some music on my phone through a MicroSD card adapter (because my bluetooth doesn't work) and it got stuck every single time I copied an album on it.

I'm not sure if all my drivers were properly installed, so I checked in the terminal if it could tell me sth about my graphics.

I also got the same laptop a while ago - unfortunately there are quite a few problems with the hardware under linux (for me - maybe you'll have better luck)

so here is what I can help with

For the Bluetooth, i think the problem is that you have it Hard blocked on your machine. Hitting Fn + F3 should toggle between all the variation of WiFi on/off, BT on/off. use the command
rfkill list
to see current state (you may need to wait a few seconds for the change)
But for me this doesn't fix BT performance - it fails to list the available devices. I tried with a BT mouse and a phone ... there are some guides you can find on the net for this - none worked reliably for me.

Other issues i have include not being able to control the screen brightness (Fn + Left/Right arrow key) or even from the display settings.

And for the WiFi it seems i managed to have it work reliably by having BT hard blocked and creating the file
/etc/modprobe.d/ath9k.conf
with contents
options ath9k nohwcrypt=1
But this means no BT mouse.
